I agree partially, but in practice, the LFP batteries should be fine (I would never trust the PowerWall 2).
Unfortunately, been looking at other alternatives, and there don’t seem to be many seamless home batteries that cut in instantly in the event of a power outage (like an online UPS) either.
The reality is though, I expect Tesla to lose this market anyway (they only just introduced the PowerWall 3 in AU… Even cheap chinese manufacturers have been using LFP for a while)
